. A ject of my invention is to provide convertible means for readily polishing floor surfaces and simultaneouslykeeping them clean so that dust, lint and foreign'material will not vbe incorporatedin the polished or waxed surface.

Various types of floor polishers have been suggested and used, including attachable members for electric suction cleaners, but the polishers, per se, omit the function of a dustless polishing action, while the latter are found to lack the necessary weight and rigidity for maintaining a high polish, and are cleaning attachments per se.

Accordingly, it has been my p urpose and accomplishment to rovide a weighted polisher adapted readi y to be attached to and removed from the nozzle of a portable electric suction cleaner, so. that the latter may be quickly converted for the combined polishing and cleaning of floor surfaces. This polishing member is constructed so that the air currents may properly be applied while the device is in use, both for drying and keeping the polished surface and polishing compound free from forei material. The polishing face may easily replaced when desired, while a resilient member is provided for augmenting the polishing action during the continued operation `of the associated suction nozzle.

The structural features, advantages and operation of my improved floor polishing appliance may best be explained in connection with the accompanying drawings, wherein: Figure 1 is a front view of a suction cleaner nozzle equipped with the removable floor polishing appliance of my instant invention,

Fig. 2 is a fragmentary view of the latter in front elevation,

Fig. 3 is an enlarged sectional view showing the left hand portion of the vnozzle with,

the appliance inserted for use,-

4 is a transverse section of the polishevice on line 1 -4,' Fig. 5.

5is a fragmentary plan view of said olis ing device or attachment, and Fig. 6 illustrates the device placed in use.

Throughout the several figures of the drawings I have employed the same character of reference to indicate similar parts.

vThe suction cleaner nozzle a of Fig. 1 may be of any desired type, but preferably the edges of the suction mouth or li s a' are ser- -rated or `rovided with air i ets 'substantially as s own. Interiorl of said nozzle at the ends thereof are ing means, such as t e recessed boss a, Fig. 3. This nozzle is well adapted for ordinary suction cleaning when used in conjunction with a portable vacuum cleaner.

The etails of the polishing attachment will be explained in connection with the enlarged showing thereof. A relativel heavy weight-member b is underslotted at to receive the substantial bearing surface c of compacted felt extending the entire length of said weight. A. felt covering c', which is replaceable, completely envelops the weight vand bearing surface; being secured between 4said.V

weight and the top plate d b means of screws e". Said top plate is provided with attaching means, present in the terminal posts d and springs d designed to enga e the bosses a" interiorly of the nozzle ang removably hold the' polishing member in position for use. The to plate is slotted at d', and the rovi ed suitable attachweight will be added to that of the attachment l in polishing oor surfaces. The bearin surfacec affords a resilient, semi-accomm gitudinally` of the nozzle, and the induced air currents around the poli cover c' throu hthe serrated lips a,a`swe asthrou h its y, in some measure, serve to dry t e ating member which supports the entire weight loniusA olishing material used and also keep the gm'shed surface free from lint and dustfrom the air.

Obviously, the attachment may be immediatel removed if the suction cleaner is to be used or its primary purpose, while the fab- Y ric covering c is alone subjected to wear when the device is used as a olisher, and this may be easily and cheaply etached and replaced as required.

Having now described land explained the operation of my improved polishing attachment, I claim as new and desire tov secure by Letters Patent, the following:

1. In a polishing attachment of the class described, the combination with an elon ated weighty member havin va longitudina slot therein, of a resilient brous member sitioned in said slot and extending beyon the walls thereof to form a supportlng art, and a removable covering enclosing saidp and resilient fibrous members to form the polishing surface for said attachment, substantially as set forth. a

2. In a floor polishing attachment, the combination with an elongated body member of substantial rigidity and weight, of a resilient member extending at an angle from the body member, a removable covering 'of olishing material disposed about said mem rs, and means. for removably attaching the device upon a suction nozzle, substantially as set forth.

3. In a polishin attachment, the combination with a longitudinally slotted member of substantial weight having perforations formed therein communicatin with said slot, of a compacted felt member is sed within said slot and extending beyon the face of the weighty member, a removable fabric covering disposed about said members and spaced away from the weighty member adjacent the felt member to afford an air space, and means for removably attaching the device for use with a suction member.

In testimony whereof I do now aix my signature.

CHARLES B. LAWRENCE.
